Motorists driving through the Baltimore region may notice several ramps to nowhere along I-95 as they travel into or out of Baltimore City. Once upon a time, these structures were part of a massive regional highway plan.We dug into the archives at the Regional Information Center (RIC) and found the 1965 Maryland State Roads Commission Recommended Master Highway Plan. The document was a grand proposal for I-70 - the major highway that begins in the Baltimore City neighborhood of Franklintown and runs east-west through Maryland to Breezewood, Pa.
